The outcomes show that the sequence of soil erosion of types of land use in different regions is different and the sequence of soil erosion of types of land use in different periods of the same regions is uncertainty ; the occurred rate of soil erosion of new wasteland is higher than that of idle wasteland for years ; the occurred rate of soil erosion of grassland is higher ; the occurred rate of soil erosion of non - irrigated farmland is high and the soil erosion intensity of land used for construction is great during construction and becomes smaller after completion

    結果表明:不同區域土地利用類型的土壤侵蝕序列各不相同,而同一區域不同時期土地利用類型的土壤侵蝕序列不確定;新出現的難利用地比長期閑置的難利用地土壤侵蝕發生率高;草地土壤侵蝕發生率偏高;耕地中旱地的土壤侵蝕發生率高;建設用地建設時土壤侵蝕強度大,而建成後土壤侵蝕強度小。
  3. Since the spring of 2001, northern china has been hit by a severe drought, and as a result, brother tians family was recently left with over sixty acres of dry farmland without irrigation facilities. other irrigated farms were not doing any better, because the local mountain stream had long ago dried up. last spring, wild grass on the mountain was dry and yellow, a scene usually seen only in autumn

  4. ( 5 ) the organic matter, total nitrogen, available phosphorus content were different between different land use types in 1980 and 1999, the order of these nutrients content in different land use types was irrigated land > rained farmland > grassland in 1980 ; the order of these nutrients content in different land use types in 1999 was vegetable land > irrigated land > rained farmland ; the changes of organic matter, total nitrogen, available phosphorus content were different between different land use types from 1980 to 1999, the order of these nutrients content change was vegetable land > irrigated land > rained farmland > grassland

    ( 5 ) 1980年,土壤有機質、全氮、速效磷三種養分含量在旱地、水澆地、荒草地三種用地類型間的變化規律是水澆地旱地荒草地,而速效鉀含量在三種用地類型之間的變化規律為旱地水澆地荒草地。 1999年,土壤有機質、全氮、速效磷含量在不同用地類型之間的變化順序為菜地水澆地旱地;而速效鉀含量的變化順序卻為旱地菜地水澆地。
  5. Water delivery has been run over 30 years. the main canal has the problem that the actual conveying capacity is very low now and the conveying capacity of the east - one main canal i only half of the design value, this lead to guaranteed real - time efficiency of the irrigation of the farmland recede greatly. the downstream has no water and crops were drought to death have been seen more times in the irrigation period, this lead to the contradictory between the upstream and downstream on water usage, moreover, the lower discharge capacity of the dry canal in irrigation period is the main cause of the actual irrigated area is only half of the design value

    經過三十年的輸水運行,目前乾渠工程存在嚴重的輸水能力低問題,其中東一乾渠輸水能力只能達到原設計的1 2 ,使農田的適時灌溉保證率大大降低,多次發生灌溉期下游見不到水而旱死莊稼的情況,造成上下游用水矛盾突出,而且灌溉期乾渠過流能力偏小,是導致實際灌溉面積僅為設計值的1 3的重要原因。
